Albert, a student researcher, varies the amount of food given to rats in an experiment to measure the effect on their learning behavior. In albert's study, the amount of food given is the independent variable.
An independent variable is under the control of the experimenter. Independent variable does not depend on the other variables involved in the experiment. Since the amount of food is varied, it is not depending on other variables like size of mice, weight, etc.
The results of the study would be expected to change if the same experiment were repeated with natural gas in the area of a decrease in the reaction time.
<h3>What is Reaction time?</h3>
This is the time frame between when a stimulus and a response or total time taken for a reaction to occur.
Natural gas produces steady amount of heat with a higher temperature which leads to a decrease in reaction time.
